Filing individual income tax returns in Arizona can be challenging, especially when it comes to filing, taxable income determination, residency, documentation, credit, deductions and more. Therefore, the Arizona Department of Revenue (ADOR) is here to help with some of the more common topics associated with the filing process.
We have three office locations.
Hours of operation are Monday through Friday, 8 a.m. – 5 p.m. (MST). Arizona tax forms are available at all locations.
Taxpayer assistance is available to customers at our Phoenix and Tucson locations. However, our Mesa location is limited to providing service for licensing of businesses and making payments. Taxpayers who require assistance with a billing they received or other tax related issues should be referred to the Phoenix or Tucson location.
The Arizona Department of Revenue will follow the Internal Revenue Service (IRS) announcement regarding the start of the 2020 electronic filing season. Because Arizona electronic income tax returns are processed and accepted through the IRS first, Arizona’s electronic filing system for individual income tax returns is dependent upon the IRS' launch date. Remember, the starting point of the Arizona individual income tax return is the Federal Adjusted Gross Income.
Taxpayers can begin filing individual income tax returns through Free File partners and individual income tax returns will be sent to the IRS starting mid-February. Tax software companies also are accepting tax filings in advance of the IRS' launch date.
Please refer to the E-File Service page for details on the e-filing process.
